Description

The Crown Jewel of Your Collection.

Presenting a breathtaking 53-carat Natural Tanzanite, a gemstone of such significant size and saturation that it belongs in a connoisseur's private collection or a high-jewelry masterpiece.

Curated by Gems of the Americas, this stone represents the pinnacle of Tanzanian mineral wealth. Mined in the foothills of Mount Kilimanjaro—the only place on Earth this gem is found—this specific piece features the highly desirable "velvet blue" with flashes of deep violet, characteristic of top-tier investment-grade Tanzanite.

The Cut: Expertly faceted in a soft Trillion cut, the stone maximizes light return and brilliance. The unique shape allows for a depth of color that shifts mesmerizingly between sapphire blue and regal purple depending on the lighting and angle (pleochroism).

Specifications:

Gemstone: Natural Tanzanite (Zoisite)

Carat Weight: 53.53 Carats

Origin: Merelani Hills, Tanzania

Cut/Shape: Trillion / Triangular Fancy Cut

Color: Vivid Deep Blue with Violet Overtone

Clarity: Eye Clean / High Transparency

Treatment: Heat (Standard for Tanzanite to bring out the blue/violet hues)

Why This Stone is Special:

Rare Size: Finding clean Tanzanite over 10 carats is difficult; over 50 carats is extraordinarily rare.

Investment Potential: As Tanzanite mines are expected to be depleted within the next generation, stones of this magnitude are becoming finite heirlooms.

Versatility: While massive, the trillion cut makes it ideal for a dramatic, custom-designed pendant or a show-stopping cocktail ring.
